The priority of the U.S. Provisional Patent Application No. 62/372,696 entitled "POWER ALLOCATION ACROSS MULTIPLE CARRIERS USING SHARED AND DEDICATED RADIO FREQUENCY SPECTRUM" filed on August 9, 2016, has been assigned to the recipient of this case. Let people.

In general, the following is about wireless communications, and more specifically about power allocation across multiple carriers using shared and dedicated radio frequency spectrum.

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, message delivery, and broadcast. These systems can support communication with multiple users by sharing available system resources (for example, time, frequency, and power). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and orthogonal frequency division multiple access Access (OFDMA) system (for example, Long Term Evolution (LTE) system). The wireless multiple access communication system may include multiple base stations, and each base station simultaneously supports communication for multiple communication devices (which may be otherwise referred to as user equipment (UE)).

Some communication modes can achieve communication between the base station and the UE through a shared radio frequency band or through different frequency spectrums (for example, a dedicated radio frequency band and a shared radio frequency band). With the increase in data traffic in cellular networks that use dedicated radio frequency bands, offloading at least some data traffic to the shared radio frequency band can provide mobile network service providers (or cellular service providers) with enhanced data transmission capacity chance. The use of shared radio frequency bands can also provide services in areas where access to dedicated radio frequency bands is unavailable. When using the shared radio frequency spectrum, the transmitter can first perform a pre-conversation listening (LBT) procedure (for example, the unused channel assessment (CCA)) to confirm that another transmitter is not using the shared radio frequency spectrum. If the LBT procedure is successful, indicating that the shared radio frequency spectrum is available for transmission, the transmitter can then use the shared radio frequency spectrum for transmission.

In some cases, the UE may use multiple concurrent carriers for transmission, where one or more carriers use a dedicated radio frequency spectrum for transmission, and one or more carriers use a shared radio frequency spectrum for transmission. In some cases, the total uplink transmission power available at the UE may not be able to support transmission on each carrier with the full power of the carrier. The UE in this case may be referred to as a power limited UE. In addition, in some cases, the UE may be scheduled to transmit higher priority control information on one or more carriers.

The techniques described are related to improved methods, systems, devices, or devices that support power allocation across multiple carriers using shared and dedicated radio frequency spectrum. In general, the described technique provides power allocation across different carriers using shared and dedicated radio frequency spectrum for power-constrained UEs. In the case that a power-constrained UE wants to transmit control information, the power allocation across different carriers can be determined based on one or more of multiple parameters, such as the type of control channel used to transmit control information, and the control to be transmitted The type of information, the timing used to transmit control information, the result of the LBT process for the carrier that uses the shared radio frequency spectrum, the timing of the LBT process, one or more other concurrent transmissions, or any combination thereof.

The foregoing content has fairly broadly summarized the features and technical advantages of the examples based on the content of this case, so that the following detailed description can be better understood. Additional features and advantages will be described later. The disclosed concepts and specific examples can be easily used as a basis for modifying or designing other structures for the same purpose of carrying out the content of this case. This equivalent structure does not depart from the scope of the attached patent application. Through the following descriptions considered in conjunction with the drawings, you will better understand the features (in terms of its organization and operation methods) and associated advantages of the concepts disclosed in this article.

As indicated above, in some cases, the UE may use multiple concurrent carriers for transmission, where one or more carriers use a dedicated radio frequency spectrum for transmission, and one or more carriers use a shared radio frequency spectrum for transmission. In addition, the UE can be scheduled to transmit higher priority control information on one or more carriers, and may be in a power-constrained situation, where the total available transmission power at the UE may not be able to support the full power of the carrier in each carrier. Transmission on two carriers. Therefore, it is possible to perform the allocation of the total available uplink transmission power across different carriers, where one or more of the carriers receive less power than the power that would otherwise be allocated to the carrier in a non-power limited scenario. In addition, in the case of using one or more carriers to transmit higher priority control information, it may be desirable to allocate additional power to these carriers in order to increase the probability of successfully receiving control information. Various aspects of the content of this case provide techniques for power allocation across multiple carriers.

When the different carriers scheduled for transmission use both dedicated and shared radio frequency spectrum, this power allocation may be more complicated, because whether the UE transmits on the shared radio frequency spectrum depends on whether the LBT procedure is clear. ). For example, if the LBT procedure is not clear, the UE may not use the shared radio frequency spectrum for transmission, and therefore has extra power available for one or more of the other carriers.

Various techniques are provided for power allocation across different carriers using shared and dedicated radio frequency spectrum. In the case that a power-constrained UE is scheduled to transmit control information, the power allocation across different carriers can be determined based on one or more of a number of parameters, such as the type of control channel used to transmit control information, and requirements. The type of control information transmitted, the timing for transmitting the control information, the result of the LBT process for the carrier that uses the shared radio frequency spectrum, the timing of the LBT process, one or more other concurrent transmissions, or any combination thereof.

Initially describe the various aspects of the content of this case in the context of wireless communication systems. Subsequently, various examples of power allocation techniques based on LBT timing and control information transmission are provided. Various aspects of the content of this case are further illustrated and described with reference to the device diagrams, system diagrams, and flowcharts related to power allocation across multiple carriers using shared and dedicated radio frequency spectrum.

FIG. 1 illustrates an example of a wireless communication system 100 according to various aspects of the content of this case. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE (or improved LTE) network. The UE 115 and the base station 105 can support multiple concurrent transmissions using shared and dedicated radio frequency spectrum. The power allocation across different carriers using the shared and dedicated radio frequency spectrum can be determined based on one or more of a number of parameters, such as the type of control channel used for transmission, the type of control information to be transmitted, and for transmission control The timing of the information, the result of the LBT procedure for the carrier using the shared radio frequency spectrum, the timing of the LBT procedure, one or more other concurrent transmissions, or any combination thereof.

The base station 105 can wirelessly communicate with the UE 115 via one or more base station antennas. Each base station 105 can provide communication coverage for a corresponding geographic coverage area 110. The illustrated communication link 125 in the wireless communication system 100 may include uplink (UL) transmission from the UE 115 to the base station 105 or downlink (DL) transmission from the base station 105 to the UE 115. The UE 115 may be dispersed in the entire wireless communication system 100, and each UE 115 may be fixed or mobile. UE 115 can also be called mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal , Wireless terminal, remote terminal, handheld device, user agent, mobile service client, client, or some other appropriate term. UE 115 can also be a cellular phone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, tablet computer, laptop computer, wireless phone, personal electronic device, handheld device, personal computer, wireless zone Loop (WLL) stations, Internet of Things (IoT) equipment, Internet of Everything (IoE) equipment, Machine Type Communication (MTC) equipment, household appliances, automobiles, etc.

The base station 105 can communicate with the core network 130 and can communicate with each other. For example, the base station 105 may interface with the core network 130 via a backhaul link 132 (for example, S1, etc.). The base stations 105 may communicate with each other directly or indirectly (for example, via the core network 130) on the backhaul link 134 (for example, X2, etc.). The base station 105 may perform radio configuration and scheduling for communication with the UE 115, or may operate under the control of a base station controller (not shown). In some examples, the base station 105 may be a macro cell, a small cell, a hot spot, and so on. The base station 105 may also be referred to as an evolved Node B (eNB) 105.

The communication link 125 may support one or more services between the devices of the wireless communication system 100. The service may include, for example, a point-to-point (for example, unicast) service between two devices (for example, between a network device 105 and a user equipment (UE) 115, between a first UE 115 and a second UE 115, etc.) , A device and a group of other devices (for example, between the network device 105 and a group of UE 115, between the UE 115 and a group of other UE 115, etc.) point-to-multipoint (for example, broadcast or multicast ) Services, or services forwarded by devices, such as those provided via a mesh network. Examples of services may include data services, data transmission services, data transmission services via Transmission Control Protocol (TCP), data transmission services via User Datagram Protocol (UDP), voice services, Voice over IP (VoIP) services, IP multimedia Services, text messaging services, text messaging services (SMS), emergency broadcast services, emergency dialing services, public alarm system services, Internet services, multimedia broadcast and multicast services (MBMS), sensor data distribution services, vehicles For vehicle services, etc., each of them can be considered a type of service. Additionally or alternatively, each type of service may include: whether the traffic associated with the service is delay-sensitive (for example, associated with delay parameters, etc.) or "critical tasks" (for example, related to acceptable and/ Or threshold error rate correlation, etc.), the quality of service (QoS) parameters associated with the service, the priority or priority level of the data associated with the service, and the recognition mode (AM) of the service, etc.

In some cases, the wireless system 100 may utilize licensed and unlicensed radio frequency bands. For example, the wireless system 100 may use long-term evolution (LTE) licensed assisted access (LTE-LAA) or LTE unlicensed (LTE-U) radio access in an unlicensed frequency band (for example, the 5 GHz Industrial Scientific Medical (ISM) band) technology. As indicated above, when operating in an unlicensed radio frequency band, wireless devices such as base station 105 and UE 115 can use LBT procedures to ensure that the channel is idle before transmitting data. In some cases, operation in an unlicensed frequency band may be based on a carrier aggregation (CA) configuration combined with a component carrier (CC) operating in a licensed frequency band. Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, or both. Duplexing in unlicensed spectrum can be based on Frequency Division Duplex (FDD), Time Division Duplex (TDD), or a combination of the two. In some cases, a component carrier may be associated with a cell, where the main cell (PCell) may use a dedicated radio frequency spectrum and the auxiliary cell (SCell) may use a shared radio frequency spectrum.

As indicated above, the UE 115 can transmit various different types of control information. One type of control information includes channel status information, which the base station 105 can collect in order to efficiently configure and schedule channels for communication with the UE 115. This information can be sent from the UE 115 in the form of a channel status report. The channel status report may include: a rank indicator (RI) requesting the number of layers to be used for downlink (DL) transmission (for example, based on the antenna port of the UE 115), a preference indicating which precoder matrix should be used Precoder matrix indicator (PMI) (based on the number of layers), and channel quality information (CQI) that indicates the highest modulation and coding scheme (MCS) that can be used. The CQI may be calculated by the UE 115 after receiving a predetermined pilot frequency signal (for example, a cell-specific reference signal (CRS) or a channel state information-reference signal (CSI-RS)). If the UE 115 does not support spatial multiplexing (or is not in a supported spatial mode), RI and PMI may be excluded. The type of information included in the report determines the type of report. Channel status reports can be periodic or non-periodic. That is, the base station 105 can configure the UE 115 to send periodic reports at regular intervals, and can also request additional reports as required. Non-periodic reports may include: a broadband report indicating the channel quality across the entire cell bandwidth, a report indicating a subset of the best sub-band selected by the UE, or a configured report in which the reported sub-band is selected by the base station 105 .

Another type of control information includes: approval information indicating successful or unsuccessful reception of the transmission at the UE 115. Such approval information may include, for example, hybrid automatic repeat request (HARQ) approval/negative approval (ACK/NACK) information. Such ACK/NACK information may include information about the successful reception of a specific transmission for the transmitted subframe, or may include block approval information, which may include information about the successful reception of multiple transmissions for multiple subframes. If the base station 105 receives a NACK for transmission or a block NACK for multiple transmissions, or does not receive ACK/NACK information within a certain period of time, the base station 105 may retransmit the associated transmission.

As indicated above, in some cases, the UE 115 may use multiple component carriers (CCs) for transmission, and these CCs use dedicated radio frequency spectrum, shared radio frequency spectrum, or a combination thereof. In addition, the UE 115 may be scheduled to transmit higher priority control information on one or more CCs, and may be in a power-constrained situation, where the total available transmission power at the UE 115 may not support the full transmission of the CC. Power is transmitted on each CC. Therefore, it is possible to perform the allocation of the total available uplink transmission power across different CCs, where one or more CCs in each CC receive a smaller amount of power than would otherwise be allocated to the CC in a non-power limited scenario. In addition, in the case where one or more CCs are to be used to transmit higher priority control information, it may be desirable to allocate additional power to the CCs in order to increase the probability of successfully receiving control information. Various aspects of the content of this case provide techniques for power distribution across multiple CCs.

When the different CCs scheduled for transmission use both dedicated and shared radio frequency spectrum, this power allocation may be more complicated, because whether the UE transmits on the shared radio frequency spectrum depends on whether the listen before dialogue (LBT) procedure is clear. For example, if the LBT procedure is not clear, the UE may not use the shared radio frequency spectrum for transmission, and therefore has extra power available for one or more CCs in other dedicated radio frequency spectrum CCs.

Various techniques for power allocation across different CCs using shared and dedicated radio frequency spectrum are provided. In the case that a power-constrained UE wants to transmit control information, the power allocation across different CCs can be determined based on one or more of multiple parameters, such as the type of control channel used to transmit control information, and the control to be transmitted The type of information, the timing used to transmit control information, the result of the LBT process for CCs that use the shared radio frequency spectrum, the timing of the LBT process, one or more other concurrent transmissions, or any combination thereof. In some examples, the first carrier using a dedicated radio frequency band is associated with the main cell (PCell). Alternatively, in the case of dual connectivity or multiple connectivity, the first carrier may be associated with the primary helper cell (PSCell). The allocation of total transmission power between the first carrier and the second carrier may also be based on whether the first carrier is associated with a PCell or a PSCell. For example, PCell can receive more power allocation than PSCell.

Figure 2 illustrates an example of a wireless communication system 200 for power allocation across multiple carriers using shared and dedicated radio frequency spectrum. The wireless communication system 200 may be an example of a portion of the wireless communication system 100 described with reference to FIG. 1. In addition, the base station 205 may be an example of one or more of the base stations 105 in the base station 105 described with reference to FIG. 1, and the UE 215 may be one or more of the UE 115 described with reference to FIG. Examples of various aspects of the UE 115.

In the example of FIG. 2, the UE 215 and the base station 205 may communicate via a communication link 220 (which may include multiple CCs 225). The plurality of CCs 225 may include a plurality of uplink CCs, a plurality of downlink CCs, or a combination thereof. The supported carrier aggregation mechanism when using the shared radio frequency band may fall into hybrid frequency division duplex-time division duplex (FDD-TDD) carrier aggregation or TDD-TDD carrier aggregation with different symmetry across component carriers. In some instances, the UE 215 may determine that multiple CCs (including one or more CCs using dedicated radio frequency bands and one or more CCs using shared radio frequency bands) are scheduled for use in the transmission time interval (TTI) transmission. The UE 215 may perform the LBT procedure to determine the availability of the shared radio frequency band for transmission during the TTI.

The UE 215 may also determine that it is power-limited for TTI, and decide to transmit control information during the TTI. UE 215 may be based at least in part on the type of control channel used to transmit control information (eg, physical uplink control channel (PUCCH), control information on PUSCH, physical hybrid ARQ indicator channel (PHICH), etc.), requirements The type of control information transmitted during TTI (for example, ACK/NACK information, CSI information, scheduling request (SR) information, buffer status report (BSR) information, other uplink control information (UCI), etc.), The timing used to transmit control information, the result of the LBT process, the timing of the LBT process relative to the TTI, one or more other CC transmissions to be transmitted during the TTI, or any combination thereof, allocated across one or more CCs for The total transmission power of the TTI.

In some cases, UE 215 may be configured by base station 205 to allocate uplink transmission power across CCs when power is limited. In some instances, the base station 205 may determine that the UE 215 can use both dedicated radio frequency spectrum and shared radio frequency spectrum for transmission, and can allocate radio resources of one or more CCs to the UE for uplink transmission during the TTI. , And the UE 215 can be configured to allocate total transmission power across CCs for uplink transmission during TTI based on one or more of the different parameters discussed above. In some instances, the base station 205 may detect through blind estimation of the total transmission power allocation in the received uplink transmission, or determine that the uplink transmission on the CC using a dedicated radio frequency spectrum has been punctured by the UE. Measure the total transmission power allocation in the received uplink transmission. The base station 205 can configure the UE 215 to perform power allocation across uplink CCs in downlink control information (DCI) or radio resource control (RRC) signal transfers, where the signal transfers are based on the parameters discussed herein. To achieve the allocation of total transmission power, or to indicate that the UE 215 will simply split the available uplink power equally among the carriers regardless of any of the parameters discussed herein.

Figure 3 illustrates an example of shared and dedicated radio frequency resources 300 for uplink power allocation across multiple carriers using shared and dedicated radio frequency spectrum. The shared and dedicated radio frequency resources 300 can be used for communication between the UE and the base station, as discussed with reference to FIGS. 1 and 2.

In the example of FIG. 3, the TTI may include multiple wireless electronic frames 305 and multiple uplink CCs that may use a shared radio frequency spectrum or a dedicated radio frequency spectrum. In this example, the first CC can use the shared radio frequency spectrum and can be scheduled for transmission in the first sub-frame 310, the second sub-frame 315, and the third sub-frame 320. The second CC can use a dedicated radio frequency spectrum and can be scheduled to use the dedicated radio frequency spectrum to transmit only during the second subframe 330, and may not be scheduled to be on the dedicated radio frequency spectrum in the first subframe 325 or the first subframe 325 Three sub-frames 335 are transmitted. The LBT program 340 may be executed before using the shared radio frequency spectrum transmission. Therefore, in this example, the LBT procedure 340 is executed for a relatively long period of time before the UE needs to transmit the second subframe 330 on the second CC. In some examples, the power allocation across the first CC and the second CC may be based at least in part on whether PUCCH or UCI piggybacking is used on the second CC (eg, piggybacking on PUCCH or UCI material with shared material).

In some instances, the UE may prioritize the transmission on the first CC and maintain a constant power from the first sub-frame 310 to the second sub-frame 315, where the remaining power (if any) is allocated to the dedicated radio frequency The second CC on the spectrum. For example, when there is no PUCCH or UCI piggyback on the second CC, the UE can use the priority order scheme. This kind of power allocation can allow the UE to use the shared radio frequency spectrum for transmission, while having access to media due to another transmitter on the shared radio frequency spectrum (due to the lack of transmission by the UE or the UE’s undetected by the LBT program of the other transmitter) Low power transmission) caused by the first CC interference or channel loss is less likely.

In other examples, the UE may partially but not completely reduce the power allocation to the first CC to reduce the possibility of other transmitters occupying the shared radio frequency spectrum, while also allocating some power to the second CC. When it comes to reducing the power of a CC, it is referring to reducing the power that would otherwise be allocated to the CC in a non-power-constrained transmission without other concurrent uplink transmissions. In this example, the amount of reduction can be selected based on one or more parameters, such as scheduled modulation and coding scheme (MCS), redundancy version identification (RV ID), power loss (PL) measurement, or other Channel status, or any combination thereof. In some examples, the UE may prioritize the transmission of the first CC and the second CC based on one or more of the parameters, and determine the amount of power reduction based on the priority.

In other examples, the UE decides whether to transmit on both the first CC and the second CC. If the UE decides to transmit on two CCs, the UE can split power equally between the first CC and the second CC. If the UE decides not to transmit on two CCs, the choice of which CC to use for the TTI may be based on other scheduled transmissions on the first CC during the TTI. For example, if the first CC is scheduled for transmission in each subframe of the wireless electronic frame 305, the UE may discard the transmission on the second CC in order to reserve the shared radio frequency band. However, if the first CC is not scheduled for transmission in subsequent subframes, the UE can choose which of the first CC and the second CC to be discarded (for example, based on the payload of the data to be transmitted, etc.) .

In some instances, the UE may allocate all necessary power to the second CC for PUCCH/PUSCH transmission, and allocate any remaining power to the first CC. For example, in the case of using PUCCH or UCI piggyback on the second CC, the UE can allocate all necessary power to the second CC. In other examples, the UE may allocate a portion of the total available uplink power to the second CC, transmit PUCCH transmissions on the second CC, and discard PUSCH transmissions on the second CC in order to save some power Power is allocated to the first CC. This kind of power allocation can increase the possibility of the UE to keep sharing the radio frequency spectrum for the duration of the TTI. In other examples, the UE may allocate part of the total available uplink power to the second CC, transmit both PUCCH and PUSCH transmissions on the second CC, and use the remaining power of the total available uplink power in the first CC. PUSCH transmission on a CC. In such an example, the ratio of the power to be allocated to the first CC and the second CC may depend on the effective load of each CC. For example, the ratio of the power to be allocated to the first CC and the second CC may be based on whether CSI is carried on the first CC (for example, non-periodic CSI).

In some examples, the control information may be scheduled for transmission on multiple CCs (eg, both the first CC and the second CC of FIG. 3) during the TTI. In some instances, the UE can load balanced power across CCs that carry control information, and can discard transmissions on any other channel (for example, PUSCH transmission), fallback from PUSCH control channel transmission to PUCCH transmission, or transfer any remaining The power is used for other channels. In some cases, the priority order for power allocation among CCs may depend on the payload of the control transmission. For example, the block ACK payload to be transmitted using the shared radio frequency spectrum can have the highest priority, followed by the triggered CSI and non-block ACK/NACK feedback to be transmitted using the shared radio frequency spectrum, and then in the dedicated or shared Only ACK/NACK feedback on the radio frequency spectrum, followed by only periodic CSI on the dedicated or shared radio frequency spectrum. In some cases, the base station can also indicate/configure the priority order to be assigned to each transmission based on some predefined rules. For example, the weighted payload size can be used to determine the priority order, where each type of UCI can determine the weight, different weights are applied to the shared or dedicated radio frequency spectrum, or any combination thereof.

In some instances, multiple CCs using shared or dedicated radio frequency spectrum may have control information and may allocate power based on the control information payload. For example, four CCs using shared radio frequency spectrum can be scheduled to transmit ACK/NACK feedback, and one CC using dedicated radio frequency spectrum can be scheduled to transmit triggered CSI transmission, and can lead based on the triggered CSI The priority of ACK/NACK feedback is used to allocate power. In some instances, the priority of CCs for power allocation can also be based on whether the control information is PUCCH control information, UCI, or control information transmitted in PUSCH transmission, where the priority of the higher priority PUCCH control information is ahead of others Control information. The ratio of the total available uplink transmission power allocated to each carrier can be determined based on the priority order of the payload on each CC. In some instances, the ratio for power allocation can be pre-established or dynamically determined based on the number/type of CCs and the effective load of the CCs.

Figure 4 illustrates an example of shared and dedicated radio frequency resources 400 for uplink power allocation across multiple carriers using shared and dedicated radio frequency spectrum. The shared and dedicated radio frequency resources 400 can be used for communication between the UE and the base station, as discussed with reference to FIGS. 1 and 2.

In the example of FIG. 4, the TTI may include multiple wireless electronic frames 405 and multiple uplink CCs that may use a shared radio frequency spectrum or a dedicated radio frequency spectrum. In this example, the first CC may use the shared radio frequency spectrum, may not be transmitted in the first sub-frame 410, and may be scheduled to be transmitted in the second sub-frame 415 and the third sub-frame 420. The second CC can use the dedicated radio frequency spectrum and can be scheduled to use the dedicated radio frequency spectrum to be transmitted only during the second subframe 430, and may not be scheduled to be on the dedicated radio frequency spectrum in the first subframe 425 or the first subframe 425 or the first subframe 430. Transmission in three sub-frames 435. The LBT program 440 may be executed before the shared radio frequency spectrum transmission is used in the second sub-frame 415. Therefore, in this example, the LBT procedure 440 is executed immediately before the scheduled transmission in the second subframe 430 on the second CC. In this case, if the LBT procedure 440 fails, it may be desirable to allocate all available power to the second CC, but in some cases the UE may not be able to adjust the power allocation in such a short period of time. In other cases, the UE may be able to perform such instant power allocation, and may allocate power between the first CC and the second CC when the LBT procedure 440 succeeds, and may allocate power only to the first CC when the LBT procedure 440 fails. Two CC.

In an example where the UE can allocate power between the first CC and the second CC when the LBT procedure 440 is successful, the UE may indicate the capability to the base station, and the base station may configure the UE to perform power allocation. Such capability may be indicated in RRC signaling, for example, and the base station may configure the UE for power allocation in RRC signaling or DCI signaling.

In instances where the UE cannot allocate power based on the result of the LBT procedure 440 immediately after the LBT procedure, the total available uplink transmission power may be pre-allocated between different carriers in some instances. In the case that the LBT procedure fails, the UE may simply not use the power pre-allocated to the first CC. The amount of total available uplink transmission power allocated to each CC may depend on whether PUCCH is present, piggybacking CSI on PUSCH, any other parameters for allocation and priority as discussed herein, or any combination thereof. In some instances, the UE may initially use the pre-allocated power based on the assumption that the LBT procedure 440 will succeed, and if the LBT procedure 440 is unsuccessful, the zoom is performed during the second subframe 430 (for example, during the second subframe 430). After one or two OFDM symbols in block 430) the uplink power allocated to the second CC. In the case of using quadrature phase shift keying (QPSK) or binary phase shift keying (BPSK) for uplink transmission, the base station may not need to be aware of changes in power allocation, because the solution to QPSK/BPSK transmission Tuning is not affected by power distribution. In the case of using higher-order modulation (for example, 16QAM, 32QAM, 64QAM, etc.), the base station may decide whether to modify the power allocation during the second sub-frame 430. Such a decision can be made, for example, by providing a fixed scaling ratio for such transmissions and having the base station blindly estimate whether to use power scaling. In other examples, the base station may indicate whether power scaling can be used in the DCI or RRC signaling. In other examples, the UE may indicate to the base station that the power will be used by puncturing PUSCH transmission (for example, two or three resource elements (RE) in PUSCH transmission) and embedding an indication for indicating scaling. Zoom.

Figure 5 illustrates an example of shared and dedicated radio frequency resources 500 for uplink power allocation across multiple carriers using shared and dedicated radio frequency spectrum. The shared and dedicated radio frequency resources 500 can be used for communication between the UE and the base station, as discussed with reference to FIGS. 1 and 2.

In the example of FIG. 5, the TTI may include multiple wireless electronic frames 505 and multiple uplink CCs that may use a shared radio frequency spectrum or a dedicated radio frequency spectrum. In this example, the first CC may use the shared radio frequency spectrum, may not be scheduled for transmission in the first subframe 510, and may be scheduled for transmission in the second subframe 515 and the third subframe 520 In the transmission. The second CC can use the dedicated radio frequency spectrum and can be scheduled to use the dedicated radio frequency spectrum to be transmitted only during the second sub-frame 530, and may not be scheduled to be on the dedicated radio frequency spectrum in the first sub-frame 525 or the first sub-frame 525. Transmission in three sub-frames 535. The LBT procedure 540 may be executed after the boundary of the second sub-frame 515 and before the transmission using the shared radio frequency spectrum in the second sub-frame 515. In this case, as discussed above with reference to FIG. 4, if the LBT procedure 540 fails, it may be desirable to allocate all available power to the second CC, but in some cases the UE may not be able to do so in such a short period of time. Adjust the power allocation. In other cases, the UE may be able to perform such instant power allocation, and when the LBT procedure 540 succeeds, the power can be allocated between the first CC and the second CC, and when the LBT procedure 540 fails, the power can be allocated only to The second CC.

In some examples, a fixed power split between the first CC and the second CC may be used regardless of the result of the LBT procedure 540. In other examples, the power scaling as discussed above for FIG. 4 may be used, for example, starting from the second or third OFDM symbol of the second subframe. In some examples, the UE may puncture the transmission of the second CC to match the puncturing in the first CC associated with the LBT procedure 540, and use the result of the LBT procedure 540 to perform power scaling, as discussed for FIG. 4 of.

Figure 6 illustrates an example of a process flow 600 for power allocation across multiple carriers using shared and dedicated radio frequency spectrum. The steps of the process flow 600 may be performed by the UE 615 and the base station 605, where the UE 615 and the base station 605 may be examples of the UE and the base station as described above with reference to FIGS. 1 and 2.

The base station 605 and the UE 615 may perform a connection establishment procedure 610 to establish an RRC connection. In some instances, different configuration parameters can be used as part of the connection establishment procedure 610, such as implementing power allocation technology between CCs based on various parameters, indicating the ability of the UE 615 to perform power allocation and reallocation, and configuring control information Or control the different priority order of the channel for power allocation, configure the different priority order of the dedicated relative to the shared radio frequency spectrum CC, and the combination thereof.

At block 620, the base station 605 may recognize the ability of the UE 615 to perform power allocation according to various techniques described herein. Such identification can be determined based on the signal transmission in the connection establishment procedure 610, or based on other information associated with the UE 615 (for example, the type of UE, or one or more other UE configurations indicating the capabilities for power allocation) . In some cases, the base station 105 may transmit a request for UE capability, and may determine the UE 615 capability based on the response to the request. The base station 605 may transmit a UE configuration 625 to the UE 615, which may indicate one or more configurations for UE power allocation. For example, the UE configuration 625 may indicate that the UE 615 is to allocate power for multiple uplink CCs based on the established prioritization of combinations of channels and payloads as discussed above. In some instances, the UE configuration 625 may be transmitted to the UE 615 as part of the connection establishment procedure 610.

At block 630, the base station 605 may allocate uplink resources to the UE 615 in both the shared and dedicated radio frequency spectrum. Such allocation may be determined based on, for example, a scheduling request (SR) or a buffer status report (BSR) received from the UE 615. Uplink resources can be allocated among multiple CCs using shared radio frequency spectrum, dedicated radio frequency spectrum, or both. The base station 605 may transmit the uplink allowance 635 to the UE 615, which may be received at the UE 615 and used to determine uplink resources for uplink transmission.

At block 640, the UE 615 may identify the shared and dedicated radio frequency spectrum carriers used for uplink transmission during the TTI. The identification may be based on the uplink allowance 635 and the allocated uplink resources provided to the UE 615. At block 645, the UE 615 may perform an LBT procedure to determine the availability of one or more CCs that use the shared radio frequency spectrum.

At block 650, the UE 615 may allocate uplink transmission power across uplink carriers based on the results of the LBT procedure, and one or more other parameters as discussed herein. This power allocation can be done before transmission, or in some instances during uplink transmission. The UE 615 may transmit an uplink transmission 655 based on the uplink power allocation for the CC used for the uplink transmission 655.

At optional block 660, the base station 605 may determine the uplink power transmission allocation. As indicated above, in the case of BPSK or QPSK transmission, the base station 605 may not decide the power allocation for uplink transmission in all cases, but may make such a decision if higher order modulation is used. In some instances, the decision on the uplink power allocation can be made via blind detection of the power allocation for uplink transmission. The base station 605 can then demodulate and decode the uplink transmission.

Discard the carrier. In some cases, power can be allocated based on determining that the control information and shared channel information are scheduled to be transmitted on the first carrier during the second subframe. In some cases, it may be based on the decision that the control information and the shared channel information are scheduled to be transmitted on the first carrier during the second subframe and only the shared channel information is scheduled to be during the second subframe. Transmission on the carrier to allocate power.

The LBT component 830 may perform a listening before dialogue (LBT) procedure to determine the availability of the second carrier for transmission during the TTI. Such an LBT procedure may include, for example, an unused channel assessment (CCA).

In some examples, the UL power allocation element 835 may allocate the difference between the total transmission power and the first portion of the total transmission power to the first carrier. In some cases, the UL power distribution element 835 may reduce the first part of the total transmission power based on the parameters associated with the transmission using the second carrier. The reduced first part is allocated to the second carrier, and the difference between the total transmission power and the reduced first part of the total transmission power is allocated to the first carrier. In some instances, the first part of the first subframe may be transmitted on the first carrier during the LBT procedure using pre-allocated transmission power, and may be reallocated across the first carrier and the second carrier based on the result of the LBT procedure. Total transmission power for TTI. In some cases, the ratio between the first part and the total transmission power is based on whether the control channel information is scheduled on one or more of the first carrier or the second carrier, or whether to use a physical uplink shared channel (PUSCH) to transmit channel status information (CSI) to determine. In some cases, TTI includes a set of sub-frames, and each of the first carrier and the second carrier is scheduled for transmission in the first sub-frame, and the LBT procedure is in the first sub-frame.

Two carriers. In some cases, the ratio of the total transmission power to be split is based on whether the second carrier is to be used to transmit CSI (for example, non-periodic CSI). In some cases, the allocation also includes dividing the total transmission power between the first carrier and the second carrier for control information transmission.

FIG. 9 illustrates a block diagram 900 of the UE communication manager 915 that supports power allocation across multiple carriers using shared and dedicated radio frequency spectrum according to various aspects of the content of the present case. The UE communication manager 915 may be an example of various aspects of the UE communication manager 715, the UE communication manager 815, or the UE communication manager 1015 described with reference to FIGS. 7, 8 and 10.

The geographic coverage area of a base station can be divided into sectors that form only a part of the coverage area. The one or more wireless communication systems described herein may include different types of base stations (for example, macro cell base stations or small cell base stations). The UE described in this article can communicate with various types of base stations and network equipment (including macro eNBs, small cell eNBs, relay base stations, etc.). There may be overlapping geographic coverage areas for different technologies.

Macro cells usually cover a relatively large geographic area (for example, a radius of several kilometers) and may allow unrestricted access by UEs that have service subscriptions with network providers. Compared with the macro cell, the small cell is a lower power base station, where the small cell can operate in the same or different (for example, authorized, unlicensed, etc.) frequency band as the macro cell. According to various examples, small cells may include pico cells, femto cells, and micro cells. For example, pico cells may cover a small geographic area and may allow unrestricted access to UEs that have service subscriptions with network providers. Femto cells can also cover a small geographic area (for example, households), and can provide UEs associated with femto cells (for example, UEs in a closed user group (CSG), UEs for users in the households) Etc.) restricted access. The eNB used for the macro cell may be referred to as a macro eNB. An eNB for a small cell may be referred to as a small cell eNB, pico eNB, femto eNB, or home eNB. The eNB may support one or more (eg, two, three, four, etc.) cells (eg, component carriers). The UE can communicate with various types of base stations and network equipment (including macro eNBs, small cell eNBs, relay base stations, etc.).

One or more of the wireless communication systems described herein can support synchronous or asynchronous operation. For synchronous operation, base stations can have similar frame timing, and transmissions from different base stations can be roughly aligned in time. For asynchronous operation, base stations can have different frame timings, and transmissions from different base stations can be misaligned in time. The techniques described herein can be used for synchronous or asynchronous operation.

The downlink transmission described herein can also be referred to as forward link transmission, and the uplink transmission can also be referred to as reverse link transmission. Each communication link described herein (including, for example, the wireless communication systems 100 and 200 of FIG. 1 and FIG. 2) may include one or more carriers, where each carrier may be composed of multiple sub-carriers (for example, different frequencies Waveform signal).
